Moros, Myrddin and Merlin Some spoilers for later SG1 seasons.

On YouTube I'm having a bit of an argument if Moros, Myrddin and Merlin are the same person. I think they are but he says they are two different characters.

I think he was known and Moros when he was on Atlantis then he went back to Earth and ascended. When he realized how big the Ori threat was he descended and built the Sangraal. At this time he was known as Myrddin or Merlin by King Arthur and his Knights of the Round Table.

If anyone could confirm this that would be great.

They're definitely the same person. From The Pegasus Project:

DANIEL
If you really are Morgan Le Fay, how do I know your intention is to help us? According to legend, you were Merlin's greatest rival.
(to Weir)
Merlin is both Moros and Myrrdin.
